iPerf is a command-line tool used to measure the maximum network throughput a server can handle. It is particularly useful when experiencing network speed issues, as you can use iPerf to determine which server is unable to reach maximum throughput.
Just to make sure I’m not missing anything, we’d have to create new disk images and distributions and reconfigure from scratch in order to take advantage of this, right?
Yes, but this is essentially what I did:
# all on one line
apt-get remove eject ethtool fbset kernel-smp kudzu lilo mkbootdisk parted raidtools redhat-config-mouse syslinux 4Suite alchemist audiofile bonobo-activation esound finger-server kernel redhat-config-nfs usbutils postgresql postgresql-libs postgresql-odbc postgresql-server
# update the system
# get rid of docs (who needs docs)
rm -rf /usr/share/doc/*
# clear out the locales you don’t use in /usr/share/locale (that’s about 66 megs originally, down to 800k if you just keep en*)

I highly recommend giving us this same information every time you make changes to the distributions so we can “follow along” on our already existing distros. Thanks for the info!

Good suggestion — I completely agree!
I forgot to mention one other change, but this will be covered in the general performance docs I’d like to write — Move your /etc/cron.daily/slocate to /etc/cron.weekly. This cron job simply runs the “updatedb” command, which indexes all the files in your filesystem for the “locate somefile” command.
If you never use the “locate” command you can move it to “cron.monthly”, or disable it all together and just run “updatedb” before using locate. The majority of high disk I/O load that occurs during the late morning hours is generate by Linodes running updatedb 🙂
